i INFORMATION FOR DEVELOPER: The following information is provided for the developer's benefit. These are not SEPA conditions. All requirements are preliminary in nature, and are based upon the preliminary site plan and the ordinances in effect at time of submittal for SEPA review. The proposal must comply with all ordinances in effect at the time a complete building permit application is filed, including those not specifically set forth herein. (Exception: For vesting under the Zoning Code, please refer to Section 44 of the Zoning Code). Contact the Planning Department for information regarding appeal processes for the requirements listed in this document. I 1. Stormwater detention/retention, quality protection, and treatment requirements for this project shall be those requirements in effect at the time of application for Public Works permits. Currently, three options for stormwater quality enhancement are presented in j the city standards. The least preferred option is allowed only if the first two options are { infeasible in the opinion of the Public Works Department. The options for stormwater I quality enhancement are, in order of preference: 1 1) An infiltration basin designed and constructed according to city standards. 2) A wetpond designed and constructed to city standards. 3) A baffle -type oil/water separator followed by a vegetated swale, both designed and constructed according to city standards. 2. When using the Santa Barbara Urban Hydrograph method to determine the wetpond volume, the entire contributing area, both pervious and impervious, must be factored into j the calculation. 3. This site needs to meet the most stringent of two different sets of detention standards, the Department of Fish and Wildlife's standards as well as the City's. City standards for the 25 year storm are more stringent than the Department of Fish and Wildlife and call for developed runoff from this storm to be released at no more than the existing 10 year peak rate. 4. City standards allow a minimum orifice size of 1 inch. 5. City standards require sodding and planting of emergent wetland species (such as cattails, yellow iris, rushes and sedges) within the wetpond treatment cell. 6. The drainage calculations need to contain information that shows the dead storage volume in the wetpond treatment cell and in the wetvault. These volumes must be equal to or larger than the required dead storage volumes in these areas. 7. City streets are to be kept clear of dirt and debris at all times during construction. Dust suppression and street cleaning must occur as directed by the Public Works Inspector. 6. Special charges for connection to the public sewer and water systems in accordance with Ordinance 1998-94 and subsequent revision are applicable. These charges are based cn projected water usage and can be substantial. The applicant is encouraged to obtain a copy of the Ordinance and determine estimated charges prior to building permit application. The actual cost shall be computed by the Public Works Department per the
